In statistics and epidemiology, logistic regression is a method of multivariable regression analysis which "describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor."[1][2]

A regression coefficient can be converted into odds ratios or relative risks by:[2]

odds ratio=eβ, where β is a regression coefficient.
